Carries axial loads acting in both directions along the shaft axis, transmitting them through two rows of balls arranged back to back within a common housing. The 52312 has a height of 64.0 mm and a mass of 2.49 kg, with a steel sheet metal cage (JP). Limiting speed is 3150 1/min, reference speed 5400 1/min. The double-direction design allows mounting where axial forces alternate or where the shaft must be axially located in both directions, without the need for a second separate thrust bearing. As this deep groove ball bearing carries axial load only, it requires a separate radial bearing to guide the shaft and cannot accept radial loads on its own. The stamped steel cage keeps ball spacing stable at the given speed range and requires grease or oil lubrication suited to the reference speed value.
